You can buy a very expensive BMW pigtail and socket and install it under the seat. Or you can buy a fused SAE pigtail like this one for a few bucks at any auto store, attach it directly to your battery, and leave the SAE connector just outside the tupperware so you can connect a battery tender...

This is really too simple for a diagram. The C650GT has two H7 headlight bulbs. One is always on, and the other is on when high beam is selected. An H7 bulb just has two contacts. So each of the two headlight connectors just has one power and one ground.

https://crashstats.nhtsa.dot.gov/Api/Public/Publication/813466 offers an assortment of interesting facts (not opinions) about motorcycle safety. It makes interesting reading. Some factors statistically associated with fatal crash involvment include No valid motorcycle license. License suspended...

Hah! In the early 1970s my wife and I had a Harley Topper scooter-- a 10 cu. in. 2-stroke with a rope pull-starter. We bought it for $50 as a second bike, used it mostly around-town for a couple of years. Even though the muffler rusted out and fell off during that time, we sold it for $50...

A foot brake makes sense, I think, if you don't have to put a foot down at stops.

I rode my 2020 C650GT with the spring preload on #1 (softest) for at least 5000 miles. This year I set it to the recommended #4. It rides and handles MUCH better. A spring preload that allows the suspension to bottom often will not give a cushy ride; it will cause hard bumps. IMHO you should be...

After a reasonably diligent web search, I'm pretty sure that the Kymco 700 scooter was last produced in 2015. I was interested to note, though, that the 550 is offered as both a 2-wheeler and a 3-wheeler. The 3-wheeler looks nice in many respects. https://kymcousa.com/2023-scooters/#

Excellent white light with crisp beam patterns on high and low on my 2020 C650GT. Low beam started to cause intermittent "LAMP" warning. Air temperature was in low 90s and electrical plug felt very hot. I removed the rubber cover and the problem stopped. Given the price and the ease of...

LEDs run hot. That is why most LED headlight bulbs have fans and/or heatsinks. See this link. I am reasonably sure that no LED headlight bulb has polarity. Certainly the Autoone H7 bulbs I bought have no polarity. The Amazon listing reads AUTOONE H7 LED Headlight Bulb, Super Bright 1:1 Mini Size...

I replaced my low beam bulb with the other Autoone LED bulb. Two notes: I replaced the high beam by simply reaching in from below. When I tried that on the low beam, everything was fine until I tried to re-engage the spring clip. One of the two spring clip legs would not engage. I finally had...

I was wrong and @Final.Drive and @speedtoys are right. I misinterpreted the tool kit hook wrench as requiring that both hooks be engaged. I finally realized that it is actually two hook wrenches on a single handle. The pulling hook must be engaged, while the trailing hook does not. Now it is not...

Two things to bear in mind with a GPS speedometer are lag and loss of signal. Depending on the sampling rate and computation algorithm, a GPS speedo may lag as much as several seconds when actual speed changes. And, of course, its behavior when the satellite signal is weak or absent is...

I bought Autoone LEDs at $30 for 2. Just used one to replace my high beam. No error codes, and light is pure white. A bit easier to install than a halogen H7, because there's no worry about oil from your fingers, and because the exterior is the same as a halogen H7-- no fan or external...

Think about this from the viewpoint of a vehicle manufacturer. If a driver believes they're going exactly at the speed limit, and a cop measures them faster, they're going to be pretty cheesed off at the manufacturer. They may even have a case for a civil suit. So the manufacturer wants the...

I've checked the speedo on my 2020 C650GT in a variety of ways, including radar signs. It is consistently from 1 to 2 MPH high at any speed. The speedo on my 2020 Toyota Camry is consistently 1 MPH high. My 2011 Burgman 650, on the other hand, had a percentage error-- about 108% high at any speed.
